Specification of Letters Patent:

. Patented Feb. 1, 1916.

Application filed August 4, 1914.- Serial No. 855,054.;

To all whom it may concern:

Be it known that we, Gnonen Bron ALLEN and VALORUS STUKELY lVEs'roo'r'r, citizens of the United States, and residents of the city of Pawtucket, in the countyof Provi dence and State of Rhode Island, have invented certain new and useful Improvements in vVinding-lliachines, of which the following is a specification.

This invention relates to awinding machine and has for its object to provide'means for laying yarn diagonally onto a spool or core, said means comprising an endless belt. having oppositely traveling. adjacent portions moving lengthwise of the cop and carrying engaging members operated to engage the yarn alternately and lead it back and forth across the face of the cop. to lay the .yarn diagonally thereonto.

A further object of the invention is to provide means for stopping the winding operation on the cop when a stickage of the yarn occurs on the swift.

The invention further'consists in the provision of means for disengaging the yarn from the guide fingers to prevent abrading of the yarn when the same stops feeding. By employing an endless belt for. producing this. traverse motion back and forth. across the face of the cop, it will-be noted that there is, absolutely no dwell from the,

feed in one direction to the feed in the opposite direction as is unavoidable where the usual cam is used for this purpose. "Then again by this construction'the mechanism is noiseless, even when-running at a. very high velocity.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed outin the appended claims.

In the accompanying drawings: Figure 1 is a plan view of our improved winding machine. Fig. 2 is a side elevation partly in section illustrating the action of the stop motion when operated by stickage on the swift. Fig. 3- is a front elevation illustrating the guide fingers and their trippers. Fig. 4 is a perspectiveview.of'one of the guide fingers pivoted to the belt. Fig 5 shows one of the tripping members. Fig. 6 shows one of the cops with the thread wound diagonally thereon.

angle.

Referring to the drawings 10 designates the side frames of the winding machine and 11,, a top rail on which are secured brackets 12 having arms 13 arranged in pairs pivotally mounted therein, the lower ends of each pair of arms receiving the spindle 14.- between them on which the cop tubes 15 are supported.

In order to rotate the cop at a uniform speed a drum 16 for each cop is mounted on and driven by the shaft 17. A. yarn or thre'adi18 is led from the swift 19 up over the guide 20 and through guide eye 51 to. the underside of the cop tube and in orderto lay the same diagonally on the cop that is to cause it to lie at an acute angle to the axis of the cop a traverse motion is provided which carries the yarnback and forth across the face of the cop while being wound thereon. 'The mechanism for producing this motion is an essential feature of our invention, the same comprising a belt 21 which may be constructed of leather, chain or of any suitable material, is led over two large pulleys 22 and 23 located at opposite ends of themachine, idler pulleys 24c and 25 being provided for leading the belt from the outside face of the v large pulleys inward so that the two parts of the belt 26 and 27 which are run in oppo site directions are adjacent each other. At

intervals all along this belt and projecting .upward from the upper edge thereof are guide fingers 28 spaced apart so that two different sets are running in opposite directions at the same time on the two different portions of the belt. Each of these fingers as will be best seen in Fig. 4 is pivoted at 29 a to the belt and each is provided with 'a' stop lug or portion 30 formed on the front of the finger and bent around to extend across the belt at a right angle thereto. and rest on the edge thereof to hold the finger in an upright position against the tension of the coil spring 31, one end of which engages Y the pin 32 in the finger and the other end engaging the pin 33 on the belt. The upper end' of each finger is turned slightly backward or in the opposite direction to its travel so as to permit the yarn to slip off when the finger is tipped at the required In order to cause these guide fingers'to release the yarn 18 at the proper time an upwardly extending tripper arm ioo 34 is rigidly secured to the frame 35with its upper end bent inward forming a flange 36 set on an angle, see Figs. 3 and 5. A trip pin 37 extends outward from the fingers so that as the latter move forward this pin will ride under the flange 36 and tip the finger to releasethe yarn at the very edge of the cop. At the instant the yarn is released by one finger traveling in one direction it is engaged by the finger on theinto the position illustrated at b Fig. 2,

in which case the yarn is liable to be broken; To prevent this breakage, a stop motion has been provided, the same comprising a broadfoot 38 the width of the swift, normally held extended into the position shown in Fig. 2 by the light spring 39. -This foot is supported on a rod 40 in the bearing 41 one end being connected to the arm 42 pivoted at 43 to the upper end of which arm is connected a rod 44* slidably mounted in the bearing 45. The inner end of this rod is positioned beneath the weighted arm 48 of the cop lifter 49 which is carried on the second arm 50 of the bell crank. This wedge shaped lifter is so constructed and arranged that when a stickage occurs and the yarn is carried partly around the swift it engages this foot'38 withdraws the end 46' from the weight arm 48 and permits the wedge 49 to.

enter between the partly wound cop on the winding drum and lift the cop 0 to the dotted position clear of the drum so that the winding will cease until the machine has received attention.

It is found in practice that should the yarn continue to be carried back and forth by the traverse motion across the face of the cop during the time that the feeding had ceased that the reciprocating action of the fingers-on the yarn would wear and injure the same therefore to prevent this the lifting member is made in such a shape as to raise the cop sufficiently so that the yarn will be lifted entirely clear of the fingers 28 permitting the traverse belt to continue without engaging or in any way injuring or affecting the yarn.

We claim:

1. In a cop winder, cop supporting means, means for rotating the cop, yarn guiding members movable rectilincally in opposite directions past the cop to alternately engage the yarn and lead it back and forth across the face of the cop whilebeing wound thereon.

2. In a cop winder, a holder for the cop, means for rotating the cop, a member having portions traveling in opposite directions along the face of the cop and means carried by the said oppositely traveling portions adapted to alternately engage the yarn and lead it back and forth across the face of the cop while being wound thereon.

3. In a cop winder, a holder for the cop, means engaging the face of the cop to rotate the same by friction, a belt having oppositely traveling portions moving lengthwise of the cop, and means carried by the said oppositely traveling portions adapted to alternately engage the yarn and lead it back and forth across the face of the cop while being wound thereon.

4. In a cop winder, means for yieldably supporting the cop, means for rotating the cop, a belt having portions traveling in opposite directions across the face of said cop,

and yieldable fingers carried by the said oppositely traveling portions adapted to alternately engage the yarn and lead it back and forth across the face of the cop while being wound thereon.

5. In a cop winder, cop supporting means, means for rotating the cop, yarn guiding members movable rectilineally in opposite directions past the cop to alternately engage the yarn and lead it back and forth across the face of the cop while being wound thereon and means for automatically stopping the cop from winding when a stickage occurs in the yarn. v

6. In a cop Winder, means for supporting the cop, means engaging. the face of the cop to rotate the same by frictional contact, yarn guidmg members movable in a straight line in opposite directions for alternately engaging the yarn to lead it back and forth across the face of the cop while being wound thereon and means for automatically separating the cop and its driver when a stickage occurs in the yarn.

7. In a cop winder, a holder for the cop, means engaging the face of the cop to rotate the same by friction, albeit having oppositely traveling portions moving lengthwise of the cop, means carried by the said oppositely traveling portions adapted to alternately engage the yarn and lead it back and forth across the face of the cop while being wound thereon and means for raising the cop from its driving means when a stickage occurs.

8. In a cop winder, cop supporting means, means for rotating the cop, opposite and continuously traveling members for alternately engaging the yarn to lead it back and forth across the face of the mp while being wound thereon and means for automatically stopping the cop from winding when a stickageoccurs in the yarn, said means also lifting the yarn from the traverse guiding means.

9. In a cop winder, means for supporting the cop, means engaging the face of the cop to rotate the same by frictional contact, op-

positely and continuously traveling members for alternately engaging the yarn to lead it back and forth across the face of the cop while being wound thereon and means for automatically removing the cop from contact with the driving means when a stickage occurs said raising means also lifting the yarn-from the traverse guiding means.
